Upgrading to the latest software packages went flawlessly, using the normal Debian/Ubuntu apt-get update/dist-upgrade/autoremove commands. Once done, there is still plenty of room left on the internal flash ROM:

This could make a pretty nifty “home monitoring and control center”. I’m not going to limit my options to this, the plan is to support a wide range of platforms – but still, this ShevaPlug sure is a comfy unit, almost like a desktop!

The NGW100 is much more widely distributed. You can even get it from DigiKey. It appears the SheevaPlug is surprisingly limited in distributors. The SheevaPlug does have the nice small already enclosed form factor which may be a big advantage for this scenario. You can get an enclosure for the NGW100 from SparkFun.
